Abstract

Papan partikel serat alami (biokomposit) dapat dijadikan alternatif pengganti material konvensional karena ramah lingkungan, sumber terbarukan dan sifatnya yang dapat terurai secara alami. Penelitian ini menyajikan studi tentang karakterisasi mekanik dan fisis papan partikel polimer diperkuat serat alam yaitu sabut kelapa dan tempurung kelapa. Variabel tetap dalam penelitian ini adalah jumlah fraksi matriks yaitu resin eposki. Variabel fraksi massa penyusun papan partikel dalam penelitian ini yaitu sabut kelapa:tempurung kelapa :epoksi adalah PP1 (30:0:70), PP2 (22,5:7,5:70), PP3 (15:15:70), PP4 (7,5:22,5:70), dan PP5 (0:30:70). Papan partikel diuji kelenturannya menggunakan mesin Universal Testing Machine mengacu pada ASTM D 7-90-03, ketangguhan impak sampel menggunakan mesin Impact Tester mengacu pada ASTM D 6110. Sampel diuji kerapatan dan pengembangan tebalnya mengacu SNI 03-2105-2006. Hasil pengujian sampel menunjukkan nilai kerapatan optimum pada sampel PP3 yaitu sebesar 1,05 g/cm3 dengan sampel diperkuat sabut kelapa dan tempurung kelapa. Hasil pengujian nilai uji ketangguhan impak optimum pada sampel PP5 yaitu sebesar 3.20 J/cm2 dan hasil pengujian nilai uji kuat lentur optimum pada sampel PP5 yaitu 382,29 Kgf/cm2 dengan sampel diperkuat tempurung kelapa. Natural fiber particle board (biocomposite) can be used as an alternative to conventional materials because it is environmentally friendly, a renewable source and is naturally biodegradable. This research presents a study on the mechanical and physical characterization of natural fiber reinforced polymer particle board, namely coconut coir and coconut shell. The fixed variable in this study was the number of matrix fractions, namely epoch resin. The variable mass fraction of the particle board in this study was coconut coir:coconut shell:epoxy was PP1 (30:0:70), PP2 (22,5:7,5:70), PP3 (15:15:70), PP4 (7,5:22,5:70), and PP5 (0:30:70). Particle board was tested for flexibility using the Universal Testing Machine referring to ASTM D 7-90-03, the impact toughness of the samples using the Impact Tester machine referring to ASTM D 6110. The samples were tested for density and thickness expansion referring to SNI 03-2105-2006. The results of the sample testing showed that the optimum density value for the PP3 sample was 1.05 g/cm3 for the reinforced coconut coir and coconut shell samples. The test results for the optimum impact toughness test value on the PP5 sample were 3.20 J/cm2 and the test results for the optimum flexural strength test value on the PP5 sample were 382.29 Kgf/cm2 with the coconut shell reinforced sample.
天然纤维颗粒板可以作为自然可再生资源和自然可生物降解的传统材料的替代品。该研究提出了一项关于机械化特性和聚合物颗粒板稳定性的研究,即椰子壳和椰子壳。留在本研究中的变量是矩阵中即eposki树脂的成分之和。本研究中的粒子板成分成分的变量:椰子壳:环氧树脂是PP1(30:5)、PP2(22.5.5:70)、PP3(15:1:70)、PP4(7.5:2:70)和PP5(30:30 0)。使用通用机器测试粒子板,使用通用机器测试机器,使用影响测试机测试粒子的灵活性。样品的密度和发展程度是基于SNI 03-2105-2006。样本测试结果显示,样本p3的PP3密度为1.05 g/cm3,样本强化了椰子壳和椰子壳。在PP5样本中测试最佳弹性测试值为3.20 J/cm2,测试结果为PP5样本中为382,29 Kgf/cm2测试值的测试结果为椰子壳样本。天然纤维板可以用作替代材料,因为它是环境友好的,是可再生的,也是自然的生物降解。这项研究展示了一项关于天然纤维再生聚合物、namely coconut和椰子壳的研究。这个研究中的固定变化是框架矩阵的编号,namely epoch树脂。这项研究中的粒子的可变质量:椰子壳:PP2 (225:7,5:70), PP2 (22.5:70), PP4 (7.5:2:70), PP5(0:5)。粒子板是通过对ASTM D -90-03的普遍测试机器推荐来测试弹性的。样本测试的是密度和厚度扩展到SNI 03-2105-2006。样本的结果表明,最初的PP3样本的最佳密度是1.05 g/cm3,用于恢复椰子线圈和椰子壳壳。最佳影响措施测试在PP5样本中值为3.20 J/cm2,而针对PP5样本的最佳弹性强度检测值为388.29 Kgf/cm2,壳壳回收样本。
